What changes in the PES to JEF conversion
PES and JEF are both home formats that can store a palette: converting from Brother to Janome keeps your colors, simply remapped to the Janome thread catalog.
- The color palette is transferred; thread references are mapped to the closest Janome catalog entries.
- The stitch count and design dimensions stay identical.
- Brother-specific metadata (extended design name, version-specific palette) is only partially carried over.
- No color check needed on the machine in most cases.

Understanding the PES and JEF formats
PES .pes · as a source file
Your PES file arrives with everything a home format can carry: the stitch sequence, dimensions in millimeters, a design name and a color palette that follows the conversion whenever the target format can store one. Versions 1 through 12 are read alike: an old PES and a recent file set out with the same information.
- BrandsBrother, Babylock, Bernina Deco
- Versions read1 through 12 (they followed Brother hoop sizes)
- ColorsPalette + thread references depending on the version
- MetadataDesign name, dimensions in millimeters
- Internal unitTenth of a millimeter
JEF .jef · as an output file
As a target, JEF serves Janome, Elna and Kenmore machines: the file automatically attaches a hoop from its table (from 80 × 80 mm up to 140 × 200 mm) and receives a palette drawn from the Janome catalog. Coming from a colorless format (DST, EXP), the default tints are checked at a glance on the machine.

Machine compatibility and dimensions
PES and JEF both store design dimensions and a hoop size: the conversion carries the original dimensions over, and JEF attaches the hoop that fits the design. A layout made for a 100 × 100 mm Brother hoop lands in its Janome equivalent, with no rescaling or repositioning.
